The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The scheme provided by the application can be used in a real scene that people charge the terminal equipment when using the terminal equipment in daily life, and for convenience of understanding, a few terms and application scenes related to the embodiment of the application are simply introduced below.

Software Interface (UEFI) between operating system and system Firmware: also known as a unified extensible firmware interface, is a standard that describes type interfaces. Such interfaces are typically used for automatic loading of a terminal device from a pre-booted operating environment onto an operating system.

With the continuous development of scientific technology, more and more scenes are used for people in daily life, the terminal equipment supplies power to the terminal equipment through a battery, and when the battery power of the terminal equipment is insufficient, the battery of the terminal equipment needs to be charged.

At present, in a battery charging technology, most of the ways of charging a battery are controlled by an ADSP chip, please refer to fig. 1, which shows a schematic view of a charging control structure of a terminal device according to an exemplary embodiment of the present application. As shown in fig. 1, the charging control architecture includes a central processing unit CPU 101 and an Analog Digital signal processing chip (ADSP) 102.

An operating system is usually operated in a central processing unit CPU 101 of the terminal device, the operating system includes a kernel layer 101a and a frame layer 101b, and the CPU 101 and the ADSP 102 are electrically connected through a GLINK bus. The charging logic in fig. 1 is controlled by ADSP 102, and in the charging process, ADSP 102 may detect the insertion and extraction of the charger, identify the type of the charger, and send a message to notify CPU 101 of the relevant charging status through the GLINK bus.

Optionally, the charging logic control may be generally directly implemented in a kernel layer in the CPU 101, where the kernel layer is operable and controlled by the ADSP, and the ADSP is loaded during charging. When the terminal equipment is in a shutdown state, the startup of the charging logic in the charging process drives the startup of the terminal equipment, and the terminal equipment is adjusted from the shutdown state to the startup state.

Referring to fig. 2, a schematic flow chart of a charging scheme provided by an example of the present application is shown. The flow may be applied to the architecture shown in fig. 1, and controlled by the ADSP of the terminal device. As shown in fig. 2, the process may include the following steps:

step 201, when the charger is inserted, it is detected whether the battery voltage is greater than 3.35 volts.

If yes, go to step 202, otherwise go to step 203.

Step 202, the boot process is executed continuously.

Step 203, the battery is charged until the battery voltage is higher than 3.4 volts.

In step 204, the computer is powered off and the power-on process is executed again.

That is to say, in the above process, if the battery of the terminal device is not over-discharged during the use process, that is, the battery voltage is greater than 3.35V, the terminal device will continue to execute the boot process when the charger is plugged to charge the terminal device, and the terminal device is directly booted. If the battery of the terminal equipment can charge the battery firstly when the initial battery voltage is less than 3.35V, and the battery is charged to 3.4V (or higher), the terminal equipment is shut down firstly and continues to be started after the shutdown because the terminal equipment is plugged with the charger. In the above scheme, when the battery is not aged or the number of times of use is not large (e.g., less than 10 times), the internal resistance of the battery is small, and when the terminal device continues to be started up, the battery voltage obtained again by the terminal device is between 3.35V and 3.4V, so that the terminal device can be started up successfully.

However, in daily life, with the increase of the number of times of using the battery, the battery may age or be damaged sooner or later, and when the battery is damaged or aged, and the like, in the above flow, step 203 is usually implemented by UEFI-mounting the ADSP, and after charging to 3.4V, the core needs to re-mount the ADSP, so that the terminal device needs to be shut down and restarted. In consideration of the aforementioned problem of battery damage or aging, in the process of performing shutdown and restarting the startup again, if the battery voltage is reduced from 3.4V to below 3.35V, the above cycle is re-entered, which causes the phenomena of failed startup and repeated restart of the terminal equipment.

In order to avoid the phenomenon of repeated restarting in the charging process caused by the aging of a battery of the terminal equipment, the starting efficiency of the terminal equipment is improved, and the application provides a solution. When the terminal equipment is in a shutdown state, a first threshold value related to the aging degree of the battery is selected during charging, and a first voltage serving as a detection condition is determined.

Referring to fig. 3, a flowchart of a method of controlling charging according to an exemplary embodiment of the present disclosure is shown. The method is applied to a terminal device, the terminal device may include a charging control architecture as shown in fig. 1, as shown in fig. 3, and the method includes the following steps:

step 301, when the terminal device is in a shutdown state and it is detected that the terminal device is connected to a charging apparatus for charging, determining to enter a first charging stage of charging the battery.

Optionally, the charging device may be a wire-type charger, or may be a wireless charging-type charger. The terminal device determines to enter a first charging phase for the battery when detecting that the charging device is inserted and charging is performed. Before entering the first charging phase, the terminal device may count that the power-on step has been performed. The first charging phase refers to a phase of charging through the unified extensible firmware interface UEFI.

Step 302, in the process of the first charging stage, if it is detected that the battery voltage of the terminal device is greater than the first voltage, the battery charging is stopped, and the first charging stage is ended, where the first voltage is determined according to the lowest start voltage at which the terminal device can be started and a first threshold, and the first threshold is related to the aging degree of the battery.

Optionally, in the process of the first charging stage, the terminal device may obtain a battery voltage, detect a magnitude relationship between the battery voltage and the first voltage, stop charging the battery if it is detected that the battery voltage is greater than the first voltage, and end the first charging stage. Optionally, the first charging phase may be ended by shutting down the terminal device, and then ending the first charging phase that has been entered.

Optionally, the minimum start voltage is a minimum voltage that the battery needs to provide when the terminal device is switched from the power-off state to the power-on state. The first threshold is related to the degree of aging of the battery. That is, the degree of degradation of the terminal device battery may affect the magnitude of the first threshold, and thus the magnitude of the first voltage. For example, the higher the degree of degradation of the battery, the larger the first threshold value.

Optionally, the first voltage may be a sum of the lowest starting voltage and the first threshold, or a value calculated by the lowest starting voltage and the first threshold according to a first formula, where the first formula may be preset in the terminal device by a developer or an operation and maintenance person. The present application does not limit the manner of calculating the first voltage.

Step 303, if the battery voltage of the battery is greater than a second voltage after the battery voltage falls back, the terminal device is started, and the battery is continuously charged, wherein the second voltage is not less than the lowest starting voltage and not greater than the first voltage.

Optionally, if the battery voltage of the battery is still greater than the second voltage after the fallback, the terminal device is started and continues to be charged. Here, the fallback refers to a process of decreasing the battery voltage after the battery stops charging from step 302. Because the battery is damaged or aged, the values after the voltage of the battery falls back may be different, so if the value after the voltage of the battery falls back is still greater than the second voltage, it indicates that the battery can ensure the normal starting process of the terminal device, and then the terminal device is started and continues to be charged.

In summary, when the terminal device is in the shutdown state, it is determined to enter the first charging stage of charging the battery; in the process of the first charging stage, when the battery voltage of the terminal equipment is detected to be greater than a first voltage, the battery is stopped to be charged, and the first charging stage is ended, wherein the first voltage is determined according to the lowest starting voltage capable of starting the terminal equipment and a first threshold value, and the first threshold value is related to the aging degree of the battery; and if the battery voltage of the battery is greater than a second voltage after the battery falls back, starting the terminal equipment and continuously charging the battery, wherein the second voltage is not less than the lowest starting voltage and not greater than the first voltage. According to the method and the device, in the first charging stage, if the battery voltage is greater than the first voltage, the battery is stopped to be charged, the first charging stage is ended, and the size relation between the returned battery voltage and the second voltage is detected again, so that the battery voltage is sufficient when the terminal equipment is restarted, the phenomenon that the terminal equipment is restarted repeatedly when the terminal equipment is charged under the shutdown condition is reduced, and the starting efficiency of the terminal equipment is improved.

In a possible implementation manner, the terminal device may further adjust the first threshold, and continue to reset the first threshold according to a cyclic manner, so as to dynamically adjust the first voltage in the charging process, thereby improving flexibility and extensibility of the scheme.

Referring to fig. 4, a flowchart of a method of controlling charging according to an exemplary embodiment of the present disclosure is shown. The method is applied to a terminal device, the terminal device may include a charging control architecture as shown in fig. 1, and as shown in fig. 4, the method includes the following steps:

step 401, under the condition that the terminal device is in a shutdown state, when it is detected that the terminal device is accessed to a charging device for charging, obtaining battery parameters of the battery, where the battery parameters are used for reflecting the aging degree of the battery.

The charging device may be a wire-type charger or a wireless charging-type charger. When the terminal device detects that the charging device is inserted and performs charging, the terminal device may initialize the UEFI, and the UEFI may obtain the battery parameters of the battery through an Analog-to-digital converter (ADC). Optionally, the battery parameter includes one or more of a battery temperature, a battery aging coefficient, a battery charge/discharge frequency, and a battery internal resistance.

Because the internal resistances of the batteries are different under different battery parameters, the voltage of the batteries drops back when the batteries drop back subsequently. For example, when the battery temperature is high, the internal resistance of the battery is high, and when the battery temperature is low, the internal resistance of the battery is low. Or, the larger the battery aging coefficient is, the more serious the battery aging degree is, the larger the battery internal resistance is, the smaller the battery aging coefficient is, the lighter the battery aging degree is, and the smaller the battery internal resistance is. Therefore, when the terminal device initializes UEFI, the battery parameters of the battery are read in advance through the ADC.

Step 402, according to the battery parameter, obtaining a first threshold corresponding to the battery parameter.

Optionally, the terminal device queries a corresponding correspondence table according to the battery parameter, and obtains a first threshold corresponding to the battery parameter. Please refer to table 1, which shows a correspondence table between a battery parameter and a first threshold according to an exemplary embodiment of the present application, where the correspondence table includes a correspondence between the battery parameter and the first threshold.

Parameters of battery	First threshold value
		Parameter of battery 1	First threshold value of
Parameter two of battery	First threshold value of two
		Parameter III of the Battery	First threshold value of three
……	……

TABLE 1

As shown in table 1, when the terminal device obtains that the battery parameter is the battery parameter three, the value of the first threshold corresponding to the battery parameter obtained by querying table 1 is the first threshold three, so as to obtain the corresponding first threshold.

Optionally, in this step, the terminal device may further determine a parameter interval of the battery parameter according to the battery parameter, and obtain the first threshold corresponding to the parameter interval according to the parameter interval. For example, the battery parameter is a battery temperature, and the terminal device may further determine a temperature interval of the battery temperature according to the battery temperature, and obtain the first threshold corresponding to the temperature interval according to the temperature interval. Please refer to table 2, which shows a correspondence table between a temperature interval and a first threshold according to an exemplary embodiment of the present application, where the correspondence table includes a correspondence between the temperature interval and the first threshold.

Temperature interval	First threshold value
		Temperature interval one	First threshold value of one
Temperature interval two	First threshold value of two
		Temperature interval three	First threshold value of three
……	……

TABLE 2

As shown in table 2, when the terminal device obtains the battery temperature, and it is determined that the temperature section of the battery temperature is the second section according to the battery temperature, the first threshold value corresponding to the temperature section is obtained by looking up table 2, and thus the first threshold value corresponding to the temperature section is obtained. For example, the temperature range is greater than 16 degrees, the first threshold value is 50mv (millivolts), the temperature range is 12 degrees to 16 degrees, the first threshold value is 75mv, the temperature range is less than 12 degrees, and the first threshold value is 100mv. When the terminal device obtains that the battery temperature is 8 degrees, the temperature interval of the battery temperature is determined to be three (less than 12 degrees) according to the battery temperature, and the first threshold determined by the terminal device is 100mv.

In a possible implementation manner, when the battery parameter includes a plurality of types, the correspondence of the correspondence table may also be increased. Please refer to table 3, which shows another correspondence table between the first battery parameter, the second battery parameter and the first threshold according to an exemplary embodiment of the present application, where the correspondence table includes a correspondence between the first battery parameter, the second battery parameter and the first threshold.

TABLE 3

As shown in table 3, when the battery parameters obtained by the terminal device include a first battery parameter and a second battery parameter, the parameter values obtained by the terminal device are a first battery parameter i and a second battery parameter i, and the terminal device obtains a first threshold value corresponding to the temperature interval by querying table 3 according to the first battery parameter i and the second battery parameter i, which is a first threshold value six.

Step 403, determining a first voltage according to the first threshold and the lowest starting voltage.

The minimum starting voltage is the minimum voltage required to be provided by the battery when the terminal equipment is switched from the shutdown state to the startup state. Optionally, the terminal device may determine the first voltage according to a sum of the first threshold and the lowest start voltage. For example, the lowest starting voltage of the terminal device is 3.35V, and the first threshold determined in the above steps is 100mv, then the terminal device sums the lowest starting voltage and the first threshold, and the resulting first voltage is 3.45V.

In a possible implementation manner, a developer or an operation and maintenance person sets a calculation formula in the terminal device in advance, and the terminal device may further bring the acquired first threshold and the acquired lowest starting voltage into the calculation formula to calculate the first voltage. For example, the calculation formula is y = kx + b, where y denotes a first voltage, x is a first threshold value, b is a lowest activation voltage, and k is a coefficient for adjusting the first threshold value. Alternatively, k may be determined by a charging current, a charging voltage, or the like of the terminal device.

At step 404, the battery voltage of the terminal device is read.

Optionally, the UEFI for initialization may read a battery voltage of the terminal device, and detect the battery voltage.

Step 405, when the battery voltage of the terminal device is not greater than the lowest starting voltage, determining to enter a first charging stage of charging the battery.

The first charging stage is a stage of charging through a unified extensible firmware interface UEFI. When the voltage of the battery is not greater than the lowest starting voltage, the voltage which can be provided by the battery cannot meet the requirement of the terminal equipment when the terminal equipment is switched from the shutdown state to the startup state, and the first charging stage for charging the battery is determined to enter, namely, the terminal equipment firstly enters the first charging stage. In a first charging phase, UEFI may load ADSP and control ADSP via UEFI to charge the battery.

Optionally, when the voltage of the battery is greater than the minimum starting voltage, the voltage that the battery can provide can meet the requirement when the terminal device is switched from the shutdown state to the startup state, and the terminal device is directly started up without entering the first charging stage and directly entering the second charging stage.

Step 406, in the process of the first charging stage, if it is detected that the battery voltage of the terminal device is greater than the first voltage, stopping charging the battery, and ending the first charging stage, where the first voltage is determined according to the lowest starting voltage at which the terminal device can be started and a first threshold, and the first threshold is related to the aging degree of the battery.

Optionally, in the process of the first charging stage, the terminal device may continue to collect the battery voltage of the terminal device, and when the battery voltage of the terminal device is greater than the first voltage, the battery charging is stopped, and the first charging stage is ended. That is, in the process of the first charging phase, the terminal device may obtain the battery voltage, detect the magnitude relationship between the battery voltage and the first voltage, stop charging the battery if it is detected that the battery voltage is greater than the first voltage, and end the first charging phase, where optionally, ending the first charging phase may refer to stopping charging the battery through UEFI control. The terminal device can acquire the battery voltage in real time or periodically.

Optionally, in the process of the first charging phase, if it is detected that the battery voltage of the terminal device is not greater than the first voltage, the battery is continuously charged in the first charging phase.

Step 407, if the battery voltage of the battery is greater than the second voltage after the first duration of the first charging phase is ended, starting up the terminal device, and entering a second charging phase.

And the second charging stage is a stage of charging through a kernel of an operating system of the terminal equipment.

After the first time period, the terminal device detects whether the battery voltage of the battery is larger than a second voltage, if so, the terminal device is started up, a system desktop is loaded, and a second charging stage is started.

That is, after the first duration of the first charging phase is finished, the terminal device needs to be powered on, run the operating system, and load the system desktop in the display screen of the terminal device. Referring to fig. 5, an interface diagram of a system desktop according to an exemplary embodiment of the present application is shown. As shown in FIG. 5, various application controls 501 are included in system desktop 500. The user may enter the corresponding application interface by clicking on the application control 501. Optionally, the system desktop is an interface displayed based on an operating system of the terminal device. For example, the operating system of the terminal device may be an android operating system, an IOS operating system, a Windows operating system, or the like.

Optionally, the charging logic of the second charging phase may be implemented in the kernel layer. That is, in the present application, the first charging phase is implemented by UEFI, and the second charging phase is implemented in a kernel layer in an operating system. In the process of the first charging stage, the ADSP is mounted to UEFI and enters a charging mode of overdischarging through the UEFI, and in the process of the second charging stage, the ADSP is mounted to a kernel layer and enters a mode of starting up to a system desktop and continuing charging.

In a possible implementation mode, the terminal equipment comprises a target register, wherein the target register is used for recording the historical charging and discharging times of the terminal equipment from a shutdown state to a startup state; before the step, the terminal equipment can also read the historical charging and discharging times of the target register; and determining the first time length according to the historical charging and discharging times. For example, the terminal device charges and discharges once each time, the number of the target registers is increased once, after the first charging stage is ended, the number of the target registers may be obtained first, the charging and discharging frequency range of the terminal device is determined according to the historical charging and discharging frequency of the terminal device, and the corresponding first duration is determined according to the frequency range, so that the corresponding first duration is waited.

Optionally, please refer to table 4, which shows a correspondence table between the first duration and the frequency range according to an exemplary embodiment of the present application, where the correspondence table includes a one-to-one correspondence between the first duration and the frequency range.

Range of times	First time length
		Range one	The first time length is
Range two	First time length of two
		Range three	First duration three
……	……

TABLE 4

As shown in table 4, after the terminal device obtains the historical charging and discharging times in the target register, the terminal device determines a time range corresponding to the historical charging and discharging times, and obtains a first duration corresponding to the time range through the lookup table 4. For example, if the frequency range is the range two, the first duration obtained by the terminal device is the first duration two.

The terminal device takes the battery voltage after the first time period as the battery voltage after the fallback. Optionally, after the first duration, the terminal device regards the battery voltage at this time as the battery voltage after the fallback. That is, the terminal device reacquires the battery voltage after waiting for the first duration, thereby obtaining a value after the battery voltage falls back after the first duration.

Step 408, if the battery voltage of the battery is greater than a second voltage after the battery falls back, the terminal device is started and the battery is continuously charged, wherein the second voltage is not less than the lowest starting voltage and not greater than the first voltage.

Optionally, the terminal device detects a magnitude relationship between the battery voltage after the pull-back and the second voltage, and if the battery voltage of the battery is greater than the second voltage after the pull-back, the terminal device is turned on and the battery is continuously charged. The setting mode of the second voltage may refer to the setting mode of the first voltage, or the setting mode of the second voltage is calculated according to a second threshold obtained from practical experience, which is not described herein again. For example, the second voltage is the sum of the lowest starting voltage and a second threshold, the second threshold is smaller than the first threshold, the second voltage is set to be 3.35v +25mv, and when the battery voltage of the battery is larger than 3.35v +25mv after the battery falls back, the terminal device is started up, and the battery is continuously charged.

In step 409, if the battery voltage of the battery is not greater than the second voltage after the fall, a new first threshold is determined according to the battery voltage after the fall.

In a possible implementation manner, in the above-mentioned detecting the magnitude relationship between the battery voltage after the pull-back and the second voltage, if it is found that the battery voltage of the battery is not greater than the second voltage after the pull-back, the terminal device may further recalculate the first threshold according to the second formula based on the battery voltage after the pull-back, and reset the calculated first threshold. For example, the terminal device increases the difference between the dropped voltage threshold and the lowest starting voltage on the basis of the first threshold.

For example, the second formula is as follows: p1= P2+ (3.35-V) +25mV. Where P1 is the new first threshold, P2 is the first threshold, and V is the battery voltage after the fall back. Taking the first threshold value as 100mV, the second voltage as 3.35v +25mv as an example, the battery voltage before the fall-back is 3.45V, the battery voltage after the fall-back is 3.33V, and at this time, the battery voltage after the fall-back is lower than 3.35v +25mv, the terminal device substitutes the battery voltage after the fall-back into the second formula, and the reset first threshold value is calculated to be 145mV. Wherein 25mV in the second formula may be empirically derived in order to prevent the determined new first threshold from increasing by too low a magnitude (e.g. 1 mV) compared to the previous first threshold.

In a possible implementation manner, the terminal device may also calculate a voltage drop value of the battery according to the voltage of the battery after the fall and the voltage of the battery before the fall, and set a new first threshold according to the voltage drop value. Wherein the voltage drop-back value is indicative of a decrease in the voltage of the battery over the drop-back duration. For example, in the above process of detecting the relationship between the voltage of the battery after the fall and the second voltage, if it is found that the voltage of the battery after the fall is not greater than the second voltage, the terminal device may further calculate the voltage fall value of the battery according to the voltage of the battery before the fall and the voltage of the battery after the fall.
